This PR adds a 20 page history to the document viewer where the user can navigate backwards and forwards in the last opened documents. The forward history is reset if the user opens a document explicitly instead of navigating back and forth. Same as a browser does, and the undo/redo stack.
The user can interact with the navigation in the following ways:
Viewmenu.Alt+LeftandAlt+Right.If novelWriter is started with the
--verboseflag, the entire history is dumped to the terminal window each time a navigation occurs. This can be used for debugging, although it is definitely verbose and may be removed at a later point.
